3.4.13. EXT-X-MAP
The EXT-X-MAP tag specifies how to obtain the Transport Stream PAT/
PMT for the applicable media segment. It applies to every media
segment that appears after it in the Playlist until the next EXT-X-
DISCONTINUITY tag, or until th
首先,这是我的代码:
SELECT --PAT.V51_PRSNPERSONNUMBER AS PSNNMBR,
(PAT.V51_PRSNFIRSTNAME + ' ' + PAT.V51_PRSNLASTNAME) AS NAME,
--ADDR.V8_PERSONHOMEADDRLINE1 AS ADDRESS,
--ADDR.V8_PERSONHOMEADDRLINE2 AS ADDRESS2,
--ADDR.V8_PERSONHOMEADDRCITY AS CITY,
--ADDR.V8_PERSONHOMEADDRSTATE
我有一些mpeg ts位域,例如传输流包:
struct ts_package_header_s {
unsigned int continuity_counter :4;
unsigned int adaptation_field_control :2;
unsigned int transport_scrambling_control :2;
unsigned int PID :13;
unsigned int transport_priority :1;
unsigned int payload_unit_start_indicator :
我是R的新手,我正在尝试为时间序列创建一个循环,但我得到了错误
attempt to apply non-function
有人知道我能做些什么来解决这个问题吗?
patient<-read.csv("Consecutive.csv",sep=";",dec=",")
pat3<-patient[1:3,]
patient3<-data.frame(pat3)
for (i in 1:128) {
AgP(i)<-ts(pat3$X(i),frequency = 1)
plot.ts(AgP(i))
}

我在db2 11.5上创建了一个数据库,然后创建了表空间,然后创建了一个表。目前一切都还好。但是,当我试图在新创建的TABLESPACE中创建索引时,它会抱怨语法错误:
CREATE INDEX SCH.TBL_PMT_ERR_NIX01 ON SCH.TBL_PMT_ERR (PMT_NO ASC, PMT_ERR_ID ASC) in TBS_EC_SINDEX;
有错误:
DB21034E The command was processed as an SQL statement because it was not a
valid Command Line Processor com
我有下面的代码,它可以很好地处理较小的数据,但当它遇到较大尺寸的记录时,它就会出错。我该如何解决ORA-01706:用户函数结果值太大的错误?
FOR r IN
(SELECT Extract(Value(p),'pmt:PayInfo/pmt:Single', r_namespace) As Address,
ExtractValue(Value(p),'pmt:PayInfo/pmt:Single/pmt:SingExtRef', r_namespace) AS extref,

我在弄清楚如何将名称空间集成到具有xmlexists的where子句时遇到了问题。查询如下:
SELECT sing_d1.sing_info_text1, sing_d1.sing_info_text2
FROM XMLTABLE(
xmlnamespaces (
'http://www.abccompany.com/Canonical' AS "abc",
'http://abccompany.com/PmtInfo' AS "pm
日安,
我有一个标量值函数,用于在SQL Management Studio中确定付款值(Excel中的PMT函数)。我导入了以下C#函数:
using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
public partial class FinancialFunctions
{
[Microsoft.SqlServer.Server.SqlFunction]
public static
我用regex来查找句子中的单词。但是下面的代码中描述的问题出现了。它在上运行得很好,但是python与非ascii变体不匹配。
import re
#ascii
pat = u"(tes?ts?)"
ttt = re.finditer(pat, u"test and tets")
print ttt.next().start()
print ttt.next().start()
# this works fine
#russian
pat = u"(молоде?цы?)"
ttt = re.finditer(pat, u"молод
我使用以下语句:
SELECT
Number As [ACCOUNT NUMBER],
SUM(CASE WHEN [Paid_Pmt_Dt] >= '05/01/2014'
AND[Paid_Pmt_Dt] <= '05/31/2014' AND [Total_Pmt_Amt] > '0' THEN Total_Pmt_Amt End) [MAY],
SUM(CASE WHEN [Paid_Pmt_Dt] >= '06/01/2014
我需要向连接添加子查询,因为一次支付可以有多个分配,所以我只需要考虑第一个匹配(其中rownum = 1)。
但是,我不确定将外部查询中的pmt添加到分配连接上的子查询是否是最好的。
我是否应该在性能命中的情况下以不同的方式执行此操作,等等。?
SELECT
pmt.payment_uid,
alt.allotment_uid,
FROM
payment pmt
/* HERE: is the reference to pmt.pay_key and pmt.client_id
